Development of a Commercial Aviation Safety Culture Survey for Maintenance Operations Technical rept

摘要

This paper describes the development and validation of a survey to assess safety culture in airline maintenance operations according to the five-factor model of safety culture proposed by Wiegmann et al. (2002). This survey parallels the survey created for flight operations (Wiegmann et al., 2003). Maintenance technicians at two FAR Part 121 scheduled passenger airlines (N = 109 and 76) completed the original version of the survey. The results yielded useful diagnostic information about the safety culture of each airline, but factor analyses indicated that the five-factor model may not be adequate to describe the data. A more complex model is proposed and modifications to the survey are suggested.
